Woke up this morning, my girlfriend was not home and no message anywhere. To embarrassed to say the time, but it was not early morning. I got the reply that she was driving, thought how does she know how to set that up. When she arrived home l asked were she was, she told me. I said about phoning her and the message, she knew nothing about it. Does this model have some kind of movement sensor? Because her's was not on.
